Claude Code | Github Copilot | V0.dev | Lovable.dev | Cursor AI React | Next.js | Vue | Angular | Python | FastAPI | Django | Claude Code | V0.dev | Elasticsearch | GraphQL | AWS | Docker 👋 I build sophisticated solutions using AI tools the right way. With 10+ years of experience and mastery of modern AI coding tools (Claude Code, Copilot, V0.dev), I deliver complex systems faster without sacrificing quality. I know when AI helps and when human expertise matters. 🎯 What I Actually Do: - AI-Augmented Development - I leverage Claude Code and V0 for rapid prototyping, then apply senior expertise to ensure production quality - Semantic Problem Solving - I think beyond features to understand your business model and build what will actually drive growth - Complex Integration Expert - Connected 50+ services (Stripe, Twilio, CRMs, ERPs) and know every edge case - Elasticsearch Specialist - Built systems processing millions of documents with intelligent search 🏆 Real Project Highlights: - 1.6GB Map Renderer - When everyone said "impossible," I built a custom tile engine that works smoothly - AI Legal Platform - Integrated GPT-4 for contract generation with proper validation and error handling - News Aggregator - Processing 1M+ articles daily with semantic search and AI summarization - E-commerce Search - Elasticsearch implementation that actually improved conversions by 40% 💡 My Unique Approach: I use AI tools as accelerators while maintaining the critical thinking they lack. This means: - 2-3x faster development without the typical AI-generated bugs - Business-focused architecture that scales from MVP to enterprise - Clear communication about what's possible and what's hype 🛠️ Tech Stack: - Frontend: React, Next.js, Vue, Angular, TypeScript - Backend: Python (FastAPI, Django), Node.js, NestJS - AI Tools: Claude Code, GitHub Copilot, V0.dev, Lovable.dev - Databases: PostgreSQL, MongoDB, Elasticsearch, Redis - Integrations: OpenAI/Anthropic APIs, Stripe, Twilio, OAuth, CRMs - DevOps: Docker, Kubernetes, AWS, Nginx ✨ Perfect Fit If You Need: - Someone who can leverage AI tools without creating technical debt - Complex problems solved with elegant, maintainable solutions - A developer who thinks like a business owner - Honest timelines and clear communication Let's discuss how I can accelerate your project with AI while ensuring enterprise-grade quality.
